A High School Student Just Built a Water Filter That Removes 96% of Microplastics, Without Expensive Equipment

Key Points:
- Mia Heller, a high school student in Virginia, developed a filtration system using ferrofluid, a magnetic liquid, to remove over 95% of microplastics from drinking water without traditional filter membranes.
- Her invention was inspired by local water contamination issues in Warrington, Virginia, where residents faced microplastic and PFAS pollution and relied on high-maintenance filtration systems.
- The ferrofluid attaches to microplastic particles, which are then extracted magnetically, allowing the fluid to be reused and reducing disposable waste.
- Microplastics, defined as particles between 1 nanometer and 5 millimeters, are increasingly found in the environment and human bodies, with uncertain but potentially serious health impacts.
- While Heller’s prototype shows promising efficiency comparable to conventional treatment plants, challenges remain in safely disposing of captured microplastics and scaling up ferrofluid production due to cost.
